Rebecca, 28, wed her fiance John Reed Loflin in Mexico on Saturday, December 3.

Rebecca wore a sleek bohemian-style wedding dress by Sherri Hill along with a sheer white cape draped across her shoulders, E! News reported. Her bouquet was comprised of white and cream roses with wildflowers and green leaves.

Based on Instagram posts from the bride's pals, Willie, 44, walked Rebecca down the aisle in a beige suit jacket while sporting his signature bandana around his head.

Rebecca wrote on social media she's "so thankful" to have gotten married in "the most beautiful place" surrounded by "family and close friends."

Sister Sadie Robertson, who previously competed on Dancing with the Stars, shared a sweet photo of Rebecca, herself and two other bridesmaids -- family members Mary Kate Robertson and Bella Robertson -- smiling for the camera.

"WOW WOW WOW what a wedding every single moment was just absolutely priceless," Sadie captioned the image. "I will cherish the memories forever! I love seeing my family grow."

The bridesmaids wore flowy, earth-toned, short-sleeved, long dresses with side cutouts. Rebecca posted a brief video of the girls dancing on her big day and said it was the "best day of [her] life."

In the days leading up to her beautiful wedding, Rebecca captured some intimate moments on Instagram, including one of John kissing her after their "truly magical" rehearsal dinner on Friday night.

Rebecca is an exchange student from Taiwan who became Willie and his wife Korie Robertsons' foster child at age 16 in 2004.

Rebecca and John got engaged on New Year's Eve 2015 when they walked a Florida beach together at sunset looking for special shells. They had met two years prior.

John popped the question with a 14-karat gold band, according to E! News, featuring a large opal set in the middle of two rows of five small diamonds adjacent to a long bar-shaped diamond.
